2012CBET.3043....1C

T.-W. Chen, M. Fraser, D. Wright, S. J. Smartt, R. Kotak, Queen's University, Belfast, report that a spectrum (range 530-975 nm; resolution about 1000) was obtained of PSN J17241023+5900069 = SN 2012an (cf. CBET 3035) on Mar. 2.28 UT with the 4.2-m William Herschel Telescope (+ ISIS). The spectrum is quite noisy, but cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2012an is a type-II supernova, with a best match to the type-IIb supernova 1993J around peak.
